Study Endpoints

Primary Endpoints

Change From Baseline in the Weekly Average of Spontaneous Bowel Movements (SBMs) During Treatment
Baseline, Weeks 1 through 4 of treatment

An SBM was defined as a bowel movement (BM) with no laxative use in the previous 24 hours. Each weekly SBM average was calculated as follows: (7 × number of SBMs) / (number of days with nonmissing data). The overall SBM rate for the 4-week double-blind treatment period was calculated as follows: (the average of the first week + the average of the second week + the average of the third week + the average of the fourth week) / 4.
